A cradle .in'dicatedgenerallyj' at 21 is lpivotally mounted inthe'supp'ortingframe' llllby means of a pivot mounting rod;.28".tra'nsversely,v disposed; and laterally,j;extend ed' from an endportion of the frame. .said pivotxrodhas.formed therein portionsoilreduceddiameter 23 -and outer'grip' portions 3B. The portions ofreduceddiameter V, are so spaced and of such width as to engage thesides. of... their front-lpostsrn when thepivotrod 12 8 ispositibiredintthe :recepta'cles' l9 'ioniop'erationz.

Portions of a pivot rod 6'! of reduced diameter similar to portions 29are clearly shown at 68 in Figures 6 and 8.

The outer end portions 38 provide convenient grips for positioning thepivot rod and cradle supported thereby at predetermined elevations inthe receptacles I9.

The cradle 27 comprises longitudinal members 3 I, transverse drum rests32 having upwardly disposed concave surfaces adapted to embrace drums orother articles to be supported and transverse stops 33 at the rear endsof said cradle. A finger 34 is secured to the drum stop, and is inwardlydisposed to overlay drum rims and thus assist in maintaining said drumson the cradle.

A windlass means is indicated generally at 35 comprising an axle 36rotatably mounted in the upwardly extended end portions of the posts II,a cylindrical reel 31, and a crank 38 for rotating the axle and reel atwill. As clearly revealed in Figs. 1 and 2, the Windlass is preferablymounted in the frame in a position superposed. and spaced from the endof the cradle opposite the pivot mountin rod '28.

It is advantageous to be able to secure the Windlass means in adjustedposition. To this end a ratchet wheel 39 is secured to the axle 31. Aratchet pawl 40 is pivotally mounted on the frame in in spaced relationto the ratchet wheel whereby said ratchet wheel may be engaged ordisengaged by the pawl as desired to secure the Windlass means.

To convert rotational movement of the reel 3'! into elevational movementof one end of the cradle 21, cables 4| are secured at one end to sa dreel and at the other to the free end of the cradle as by means of studs42.

Fig. 2 reveals elements of the hoist in end elevation for greaterclarity. The flan es 26 on the handle means 23 are clearly revealed in aposition overlapping the rear posts I i to en age the same upon upwardmovement of the handles.

A drum 43 having a spigot 44 is shown in in light line construction in asup orted position on the cradle of the hoist and displaced from thehorizontal, as for emptying purposes. The side elevation of the deviceof the present invention. as shown in Fig. 3, also reveals the handlemeans 23 in operating position.

Modified supporting frame A modified form of the present invention isillustrated in Fig. 4. For the front osts M in this modification, posts45 of somewhat dissimilar construction are substituted. Said posts 45are of box-like structure and have longitudinal openings 46 formedtherein in commu ication with the hollow interiors of the same. Theposts and openings comprise guide ways. Blocks 4! are slidably engagedwithin the box posts 45, as indicated in Fig. 5, maintained within saidposts but freely positionable longitudinally thereof.

In this modified form. guide rod ill is substituted for the pivot rod28. Said guide rod pivotally mounts the cradle 2! and abuts and isweldably secured to the slide blocks 41.

The posts 45 differ further from the posts l 2 in that they extendupwardly from the top stringer l6, as do rear posts I I, in order toprovide greater freedom of movement of the cradle and supported objects.

A second Windlass means 59 is rotatably mounted in the upwardly extendedend portions of the posts 45 in a substantially parallel relation to thefirst Windlass means 35. Said second windlass means 49 comprises an axle50 rotatably mounted in said upper end portions of the posts 45, a reel5| mounted thereon between said posts and a crank 52 for impartingrotation to the said axle and reel. A ratchet wheel 53 is secured to,the Windlass means and a ratchet pawl 54 is pivotally mounted on thesupporting frame in spaced It is frequently desirable to secure the drumin the cradle during the manipulating opera-- tions. To this end amodified cradle 5? somewhat similar to the cradle 2'! is illustrated inFigures 6, 7, and 8. The drums to be secured being of varying length, asecuring means adjustable in relation to such length, is provided.

The modified cradle 51 has longitudinal members 58 somewhat similar tomembers 3! in the already described embodiment of the present invention.Members 58, however, are preferably constructed of channel-ironpositioned on edge, said channel iron having a web portion 59 an upperlip portion 50 and a lower lip portion 6!. as shown in Fig. 8. The lowerlip portion BI is serrated to provide ratchet teeth 62 as illustrated inFig. 6.

The said longitudinal members 58 are secured in spaced relation to eachother by means of drum rests 63 similar to drum rests already described.A drum stop 64, similar to stop 33, also already described, is securedtransversely to the cradle at the rear end thereof. A finger 65 ismounted on the stop 64 and is directed inwardly relative to said cradleto overlay rims of supported drums and thus assist in securing said drumon the cradle. A tie piece 65 is secured to the longitudinal members 58at the front end of the cradle to preclude spreading of the same.

A. pivot rod 61, somewhat similar to pivot rod 28. is employed to mountthe cradle in the supporting frame as described. Said pivot rod 6'! alsohas portions of reduced diameter 68 for engaging receptacles in thesupporting frame, such as l9.

An adjustably positioned framework 69 comprises a rear transverse strutelement 10, a front transverse strut element H and runner elements 12.The rear strut 1D has an upper concave surface to permit said strut toslide under a drum supported in the cradle. The front strut H isnotched, as at 13, to permit convenient access to the spigot of asupported drum. The struts are of such length as to hold the runnerelements 72 in engagement with the channels of the longitudinal members58 and yet not of such length as to cause said runners to bind therein.

Bolt elements 14 are provided to engage the ratchet teeth 62 andmaintain the framework 59 in adjusted position. Said bolts comprise abeveled engaging portion 15, a body portion 16, and convenientlydisposed thumb tabs 11. The body portions 16 of said bolts have formedtherein longitudinal spring slots 18.

tibii pe mitting ttw' atid retcnet teeth The operation of a hoistconstructed as described is as fdllb'tts:

The cradle 2'! is pivotally mounted in the suppdrtirfgfr'an'ie I at aselected heightby engaging the portions of reduced diameter '29 inselected receptacles f9? Thepajwllfl is released-ens the free end ofsaid cradle lowered-a s far as possible. So'positioned the cradle isinatilted position as shown in Fig. 2 its rear,=-orfree, end resting atg early ground level, y

Drum 63 is positioned on the cradle by tipping the same awayfrdm thehoist; pas'sing the stop 33 under the bottom thereof, and then tiltingthe drum intothehoist to recline the same upon 'the barrel rests 32. Thefinger 34 then overlays the rim of the drum and assists in maintainingthe same on the cradle.

The spigot 44, :being on the upper end of the barrel, is then in anexposed position at the front end of the hoist as shown in Fig. 3. Ifthe spigot is not in the illustrated lower position, the drum may beconveniently rotated on the drum rests until in operating position.

The crank 38 is turned to rotate the Windlass means, roll the cables 4|on the reel thereof and thus e evate the rear end of the cradle. Thepawl 40 is permitted to engage the ratchet wheel 39 when the cradle isin the desired attitude relative to said frame.

It is obvious that this provides a convenient displacing ocf the drumfrom the horizontal as for emptying purposes.

To move the hoist and supported drum, the handles 23 are extended asshown in Fig. 3 and the flanges 26 are caused to engage the posts H topermit the raising of the rear end of the hoist by lifting on thehandles. Thus supported by the handles 23 and wheels 2|, said hoist andsupported drum may be trundled about at will. When not in use thehandles are folded down out of the way as shown in Fig. 1 and Fig. 4.

When the hoist is employed to raise an object such as a drum, as forloading the same on an elevated platform, the pivot rod 28 is preferablyplaced in receptacles I9 nearly adjacent, but

Operation .0 the cradle modification The modified cradle 51 is operatedsubstantially as is the preferred embodiment of the same but with theseadded advantages. When it is desired to secure objects, such as drums,on the cradle the bolts 14 are retracted from engagement with theratchet teeth 62 by pressing the thumb tabs 11 toward each other and theframework 69 is slid forward in the cradle a sufiicient distance topermit the drum to be loaded. The drum is positioned on the cradle 51 inthe manner already described for cradle 21. The drum is then secured onthe cradle by thrusting the framework 69 rearwardly causing the fingersB4 to overlay the top lip of the drum and finger B5 to overlay the lowerlip thereof much in the manner of finger 34 already described. As theframework is thrust rearwardly the bolts i l ratchet rearwardly on theteeth 62 and oppose any forward movement of said framework when inadjusted position.

To release a drum so secured in position, the thumb tabs 11 are pressedinwardly to retract the bolts 14 and the framework is released fromengagement.

Although I have herein shown and described my invention in what I haveconceived to be the p aided cause-creme most practical and preferredembodiments, it is recognized that departures may be made therefromwithin the scope of my invention, which is not to be limited to thedetails disclosed herein, but is to be accorded the full scope of theclaims so as to embrace any and all equivalent devices and systems.
